lifestyle changes, such as exercise programmes and relaxation techniques

Exercise in particular has been found to have a number of important benefits for people with fibromyalgia, including helping to reduce pain.

What causes fibromyalgia?

The exact cause of fibromyalgia is unknown, but it's thought to be related to abnormal levels of certain chemicals in the brain and changes in the way the central nervous system (the brain, spinal cord and nerves) processes pain messages carried around the body.

It's also suggested that some people are more likely to develop fibromyalgia because of genes inherited from their parents.

In many cases, the condition appears to be triggered by a physically or emotionally stressful event, such as:

an injury or infection

giving birth

having an operation

the breakdown of a relationship

the death of a loved one

Who's affected

Anyone can develop fibromyalgia, although it affects around 7 times as many women as men.

The condition typically develops between the ages of 30 and 50, but can occur in people of any age, including children and the elderly.

It's not clear exactly how many people are affected by fibromyalgia, although research has suggested it could be a relatively common condition.

Some estimates suggest nearly 1 in 20 people may be affected by fibromyalgia to some degree.

One of the main reasons it's not clear how many people are affected is because fibromyalgia can be a difficult condition to diagnose.

There's no specific test for the condition, and the symptoms can be similar to a number of other conditions.

Support groups

Many people with fibromyalgia find that support groups provide an important network where they can talk to others living with the condition.
